Several months ago, we reviewed Corsair and OCZ DDR550. Those memories were based on the 2nd generation Hynix memory chips, called Hynix B, and offered the highest memory speeds that we had tested up to that point. Hynix has continued development of the B chip, and we're taking a look at two new memories based on the latest Hynix B chips. Both are rated at DDR550, and both extend memory speed to even higher levels than what we saw in the last generation.
